LUBRICATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 772,153, dated October 11, 1904. Application filed June 8, 1904. Serial No, 211,673. (No model.)

To all whom it may concern.-

Be it known that I, J osErH F. JOY, a citizen of the United States of America, residing at Neweagle, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification, reference being had therein to the accompanying drawings. 7

This invention has relation to lubricating devices, and has for its object to provide a device of this character wherein novel means is employed for lubricating the axles and wheels of cars.

Another object of my invention is to provide a lubricating device which will be automatically operated by the car that is to be lubricated by the device, and in connection with the lubricator I have employed novel means whereby the amount of lubricating oil or material which is to be ejected upon the axle of thecar is automatically regulated.

Briefly described, my improved lubricating device consists of providing oil-receptacles upon the ends of the axles of a car and of mounting a suitable reservoir adjacent to the cartrack. Below the track I mount a suitable pump whereby a lubricating oil or material may be forced into the oil-receptacle carried by the axles of the car, novel means being constructed in connection with the pump and the reservoir whereby the ejection of the lubricating oil or material into the oil-receptacle will be operated by the movement of the car.

All of the above construction will be hereinafter more fully described, and referring to the drawings accompanying this application, wherein like numerals of reference indicate like parts throughout the several views, Figure 1 is an end view of my improved device, showing a portion of the same in section; and Fig. 2 is a vertical sectional view of a carwheel, showing my improved oil-receptacle mounted thereon. Fig. 3 is an enlarged perspective view of the oil-receptacle.

In the accompanying drawings I haveillustrated my improved device as employed in connection with a mining-car, and the reference-numeral 1 indicates one of the axles of the mining-car upon which the body 2 of the car is supported, and the reference-numerals 3 3 indicate the wheels mounted upon the ends of the axle, one of said wheels being clearly shown in Fig. 2 of the drawings. The hub portion 3 of these wheels is provided with a port 4, which communicates with the bore 5 of the hub, and'upon the end of the axle 1 I secure an oil-receptacle 6 by means of a key or pin 7, which passes through the end of the axle, and in the top of this oil-receptacle I provide a screw plug 8, whereby the key or pin may be placed in position upon the end of the axle.

The reference-numeral 9 indicates an aperture which is formed centrally within the side of the oil-receptacle 6, and it is through this aperture that the lubricating oil or material is adapted to be ejected. The other side of the receptacle carries a pipe 8, which protrudes in the port 4 and through which the oil passes.

In the road-bed upon which the car travels and directly beneath a tie or suitable support l0,upon which the rails are secured, are mounted pumps 11 11, and while I have herein shown in Fig.1 of the drawings a lubricating device upon each side of the tracks it is only deemed necessary to describe the operation of one of the devices employed for lubricating one of the wheels upon one side of the track.

. Between the rail-sections I mountavertical rod 12, which passes through the tie 10 and protrudes a short distance above the head of the rail, as indicated at 14, this rod extending downwardly into the pump and serves the function of the piston-rod. To the lower end of the rod is secured the piston15, which reciprocates vertically within the pump 11, and connected to the lower end of the pump is a pipe 16, upon which is mounted a check-valve 17, this pipe leading to a suitable reservoir 18, elevated above the track. Also connected to the lower end of the pump 11 is a pipe 19, having a suitable check-valve 20, this pipe extending vertically, as indicated at 21, and then at right angles, as indicated at 22, this rightangled portion of the pipe being in alinement with the aperture 9 of the oil-receptacle 6, and upon this pipe-section 22 is mounted a valve 23, the outer end of the pipe-section being provided with a nozzle 24.

The reference-numeral 25 indicates a standard which is mounted upon the tie or support upon the inner side of the track, and pivoted to this standard is a lever 26, which is also pivoted, as indicated at 27, to the vertical rod 12, and to the outer end of the rod 26 is pivoted, as indicated at 28, a vertical rod 29, which is connected to the operating-lever 30 of the valve.

The reference-numeral 31 indicates a spring which is interposed between the top of the pump-cylinder and the piston 15, this spring being adapted to normally hold the piston in the upper end of the cylinder.

The operation of the different parts of my improved lubricating device is as follows: Upon a car passing over the track adjacent to the vertical lever 12 the wheels will depress the vertical rod, forcing the piston 15 downwardly within the pump 11, and any lubricating material or oil in the pump will be forced through the pipe 19, pipe 21 to the pipesection 22, from where it is ejected through the nozzle 24 into the oil-receptacle 6, from where it flows into the port 4, communicating with the bore 5 of the hub of the wheel. Upon the vertical rod 12 being depressed by the wheel it carries downwardly with it the lever 26, which operates the valve 23 to open the same and permit the lubricating-oil to be forced through the nozzle 24:. When this operation takes place, the spring 31 is expanded, and upon the car-wheel releasing the rod 12 the spring will return the piston to the top of the cylinder, at which time another supply of lubricating-oil will be emitted to the pump 11 from the reservoir 18 through the pipe 16, the check-valve 17 preventing the oil from returning in said pipe when the piston 15 descends and the check-valve preventing the oil from reentering the pump after the piston has descended and forced the same on its way to the nozzle 24. As heretofore stated, the construction upon the opposite side of the track is similar to that just described, and it will be noted that the general arrangement of the pipes, the position of the reservoirs, and the mechanism employed to operate the device may be slightly changed without departing from the general scope of the invention.

What I claim, and desire to secure by Letters Patent, is-

1. In a device of the character described,

the combination with an oil-receptacle carried upon the end of the axle of a car, of a pump located in the road-bed upon which the car travels, a pipe leading from the pump to a point adjacent the line of travel of said receptacle, a valve located in said pipe, a reservoir in communication with said pump and means actuated by the car to open said valve and to operate said pump and eject a lubricating-oil into the oil-receptacle of the car.

2. In a device of the character described, the combination with an oil-receptacle carried by the axle of a car, of a pump, a reservoir in communication with said pump, a nozzle supported in alinement with said oil-receptacle and in communication with said pump, a pipe through which such communication is efiected, a valve on said pipe, means actuated by the car to open said valve and eject a lubricating-oil in said oil-receptacle, and means actuating the first-named means to return the pump to its normal position and close said valve.

3. In a device'of the character described, the combination with a car-axle, of an oil-receptacle carried by said axle, a pump located in the road-bed upon which the car travels and beneath the rails, a reservoir in communication with said pump, a nozzle arranged in the plane of travel and outside of the line of travel of said oil-receptacle and communicating with said pump, means actuated by the rim of the car wheel to operate said pump to eject a lubricating-oil into said oilreceptacle.

1. In a device of the character described, the combination with an oil-receptacle carried by the axle of a car, of a pump, a reservoir communicating with said pump, a nozzle arranged in alinement with said receptacle and communicating with said pump, a valve carried by said nozzle, a rod connected to the piston of the pump and adapted to contact with the rim of the wheel and actuated by the car to operate said pump and means actuated by the said rod to operate said valve.

In testimony whereof I afiix my signature in the presence of two witnesses.
